Keltham is internally a bit unhappy he didn't get a chance to talk to Oldguy before, obviously, Oldguy read Keltham's transcripts, including for example a recent report obviously filed by Broom specifically; and Keltham notes to himself that everything here is being Rephrased to the Alien's Terms so that it Appeals To Keltham, and, this being Golarion, is possibly skewed along the way.
"Several questions, but first, I note that talking about 'a Chaotic Evil human who values no habits of coordination won't kill for a copper piece' is, one, obviously shaped to appeal to Keltham specifically, two, something that sounds visibly false since not killing for a copper piece is exactly one of the habits of coordination, that you don't destroy a lot of someone else's value in exchange for a tiny gain yourself. Consider not trying as hard to rephrase things in the Alien's own terms and saying things you think are more plainly true and letting me do some of my own work of translation. The more you try to talk in my unfamiliar conceptual language, the more liable you are to say things that parse out false in my language."
"Next, what exactly was Good paying Asmodeus to do back in the beginning of things? Make devils from the living as opposed to what, the dead? I didn't parse that part."
